Groundwater contribution to nutrient export from the Ellen Brook catchment

[摘要] The project was aimed to develop a conceptual groundwater model of the Ellen Brook catchment to improve understanding of the connectivity and travel times of water and nutrients in groundwater systems from different parts of the catchment, as well as their interaction with surface waters. The study area was delimited by the surface water catchment of Ellen Brook. Indirect indicators were used to identify the groundwater contribution to Ellen Brook, including analysis of baseflow, groundwater residence time and remotely sensed data to delineate groundwater discharge zones. Review and analysis of water flow and quality data were conducted for the surface and groundwater of the Ellen Brook catchment. This was complemented with some additional field work designed to further understand the hydrogeological characteristics of the system.
